I was wondering if anyone had experience measuring the embodied carbon of the Use Stages (B1 to B5) in OneClick LCA for North American projects?
Stage B1 (use phase) can be measured under the “emissions and removals” query, under which refrigerant emissions, concrete carbonisation, and vegetation carbon withdrawals can be calculated. How do we go about estimating these quantities?
OneClick does not provide an option to calculate Stage B2 (maintenance phase), and when we reached out to them we were told that in some schemes this can be estimated based on the fuel used by cars which have to drive to locations to maintain things, or as a percentage of B3 emissions, however neither estimations provide really reliable data. Has anyone used this method or a different one?
Lastly, is there a rule-of-thumb for the repair rate of typical building materials? This is required for Stage B3 (repair rate phase).
Any information would be greatly appreciated!
